Good Luck (Korean: 굿럭) is a manhwa by E-Jin Kang (강이진) published by Daewon C.I.
"Good Luck is a very grounded, authentic feeling book that takes what seems like standard shoujo story clichés and makes them fresh and new simply by injecting realism into them."
[11] "Most teenagers can identify with betrayal, love, and the need to put up a false front inside school walls.
If it could pick one plot point and work with it, Good Luck would be a much stronger manhwa."
[13] "Good Luck by E-Jin Kang is a romance and drama manhwa (Korean comics), or better yet, a romantic, teen melodrama."
